Juan Victor Séjour Marcou et Ferrand (June 2, 1817 – September 20, 1874) was an American-born Creole of color and writer.

Although he was mostly unknown to later American writers of the nineteenth century, his short story "Le Mulâtre" ("The Mulatto") is the earliest known work of fiction by an African-American author.

Juan Victor Séjour was born on June 2, 1817, in New Orleans to François Marcou, a free man of color from Saint-Domingue (today's Haiti), and Eloisa Philippe Ferrand, a New Orleans-born quadroon.

There he met members of the Parisian literary elite, including Cyrille Bissette, publisher of the black-owned journal La Revue des Colonies.

Its condemnation of slavery, however, anticipates the work of such 19th-century African-American writers publishing in English as Frederick Douglass and William Wells Brown.

This is best exemplified by his play The Brown Overcoat, a typical artificial comedy of the time period with witty comments and puns, avoiding race and social commentary entirely.
